Description

Technical Field

[0001] The present invention relates to the technical field of file management and storage, in particular to an archive management file taking and placing device. Background Art

[0002] File storage cabinets are cabinets used to store documents and materials. They usually refer to boxes with lids and cabinets with doors. They are generally made of wood or metal. Some are also made into modular types, separated into boxes and stacked into cabinets. They can usually be used to store important documents, materials, archives, insurance policies, etc. When archival documents are usually stored, the files are usually packaged in file boxes and placed in the file cabinet for stacking.

[0003] However, there are still some problems when using the existing file management file retrieval and placement equipment:

[0004] There is a file storage cabinet with Chinese patent publication number CN208510341U, which includes a cabinet body and a cabinet door, and the cabinet body and the cabinet door are connected by hinges. However, the existing file storage cabinets usually stack files to prevent them from being stored, but cannot fix archival files. If all archival files are stacked in one layer, the file cabinet will be tilted and collapsed when it is slightly bumped or moved, and the files will be stacked or even scattered, causing chaos. The stability of the file storage cannot be guaranteed, and it is inconvenient to take the files. If all the files are neatly stacked, the files will be in a state of being close to each other, which is inconvenient to extract the files from them. In the process of taking the files, they will cause friction with other files, which is easy to cause wear and damage to the external file bags or files.

[0005] In response to the above problems, an innovative design was carried out based on the original archive management document retrieval and placement equipment. Summary of the Invention

[0006] The purpose of the present invention is to provide an archive management document retrieval and placement device to solve the problems raised in the above background technology, such as the low stability of existing documents after storage, the easy scattering and disorder of documents due to collision with cabinets or movement of cabinets, the inconvenience of taking documents, and the easy wear and tear of the outside of other documents.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an archive management document retrieval and placement device, comprising a cabinet:

[0008] Universal wheels are bolted to the four corners of the lower end of the cabinet, and a sealed door is hingedly connected to the front end of the cabinet, and a glass plate is embedded in the sealed door;

[0009] The inner walls on both sides of the cabinet are vertically provided with first sliding grooves, and sliding blocks are slidably connected inside the first sliding grooves;

[0010] There are two groups of sliding blocks, and the adjacent end surfaces of the two groups of sliding blocks are provided with a primary sliding groove;

[0011] A file storage plate is slidably connected to the inside of the first-level slide, and a storage slot is provided on the upper end of the file storage plate, and a partition is arranged in an array on the upper end of the file storage plate;

[0012] A movable groove is provided on the upper end of the file storage plate, and a threaded screw rod is provided inside the movable groove.

[0013] Preferably, the sliding block and the first sliding groove are both designed as a "T"-shaped structure, a first worm is passed through the lower inner end of the sliding block, and the first worm is connected to the sliding block bearing;

[0014] The sliding block has an internal bearing connected to a bidirectional threaded rod, and two sets of positioning rods are provided inside the sliding block, and the outer ends of the two sets of positioning rods respectively pass through the outside of the front and rear end surfaces of the sliding block, and the two sets of positioning rods are threadedly connected to the bidirectional threaded rod;

[0015] A first worm gear passes through the middle of the bidirectional threaded rod, and the first worm gear is meshed and connected with the first worm.

[0016] By adopting the above technical solution, the first worm and the bidirectional threaded rod can be driven to rotate by rotating the first worm, and the two sets of positioning rods can be driven to move in opposite directions by the bidirectional threaded rod.

[0017] Preferably, positioning holes are provided inside the first sliding groove, and the positioning holes are distributed in an equidistant array inside the first sliding groove. The positioning rod extends into the first sliding groove and is engaged with the positioning holes to form a limiting structure.

[0018] By adopting the above technical solution, through the setting of multiple groups of positioning holes, the position of the sliding block can be restricted when the positioning rod is engaged with the positioning hole, and the positioning rod is connected to positioning holes of different heights to adjust the height of the sliding block, which is convenient for adjusting the positions of multiple groups of file storage plates according to the different heights of the files.

[0019] Preferably, the internal shaft of the primary chute is connected to two sets of limiting rollers, and the limiting rollers are in contact with the upper and lower end surfaces of the file storage plate;

[0020] A limiting plate is provided at the rear end of the first-level chute, and the front end of the limiting plate contacts the rear end surface of the file storage plate. The rear end of the limiting plate is fixedly connected to a first return spring, and the rear end of the first return spring is fixedly connected to the inner wall of the first-level chute.

[0021] By adopting the above technical solution, the stability and smoothness of the file storage plate during movement can be improved by setting the limiting roller. At the same time, the setting of the first return spring can automatically pop the file storage plate forward when the movement of the file storage plate is not restricted.

[0022] Preferably, the two ends of the threaded screw are fixedly connected to a second worm, and the second worm passes through the left and right ends of the file storage plate;

[0023] The outer end key of the second worm is connected with a transmission gear, and a transmission rack is provided inside the primary sliding groove, and the transmission rack is meshed with the transmission gear.

[0024] By adopting the above technical solution, through the meshing of the transmission rack and the transmission gear, when the file storage plate slides inside the first sliding groove, the transmission rack can drive the transmission gear to rotate, and drive the second worm and the threaded screw to rotate synchronously through the transmission gear.

[0025] Preferably, a reciprocating screw is passed through the interior of the outer end of the file storage plate, and a second worm gear is connected to the bearing at the lower end of the reciprocating screw, and the second worm gear is meshed with the second worm gear;

[0027] By adopting the above technical solution, through the setting of the reciprocating screw, when it rotates to a certain angle, it can drive the limit block to move upward and extend to the inside of the secondary limit groove, thereby limiting the range of movement of the file storage plate.

[0028] Preferably, an inner ratchet is provided inside the second worm gear, a pawl is connected to the lower end shaft of the reciprocating screw, and a second return spring is fixedly connected between the end of the pawl and the reciprocating screw, and the pawl is meshed with the inner ratchet.

[0029] By adopting the above technical solution, the inner ratchet and the pawl cooperate to drive the second worm and the reciprocating screw to rotate normally when the second worm rotates forward, and the second worm wheel does not drive the reciprocating screw to rotate synchronously when the second worm rotates reversely.

[0030] Preferably, a sliding plate is provided in the internal array of the movable groove, and the sliding plate is slidably connected to the movable groove, the upper end of the sliding plate is fixedly connected to the movable plate, and the lower end of the sliding plate is threadedly connected to the threaded screw;

[0031] The left end of the movable plate is provided with a clamping plate, and the right end of the clamping plate is fixedly connected to a limiting rod, and the right end of the limiting rod passes through the movable plate, and the front and rear ends of the clamping plate are designed as arc-shaped structures.

[0032] By adopting the above technical solution, through the connection between the sliding plate and the threaded screw, the threaded screw is synchronously driven to rotate when the file storage plate moves, thereby driving multiple sets of sliding plates, movable plates and clamping plates to move synchronously, so as to clamp the file documents inside the storage slot, thereby improving stability and preventing tilting and accumulation.

[0033] Preferably, the right end face of the clamping plate is fixedly connected to the first fixed seat, the left end of the movable plate is slidably connected to the second fixed seat, and a connecting rod is axially connected between the first fixed seat and the second fixed seat, and the connecting rod forms a rotating structure with the first fixed seat and the second fixed seat respectively.

[0034] By adopting the above technical solution, the first fixing seat, the second fixing seat and the connecting rod cooperate to enable the clamping plate to move horizontally, thereby providing a buffer when clamping documents and files.

[0035] Preferably, a sliding guide rod is fixedly connected to the interior of the movable plate, and the sliding guide rod passes through the second fixing seat, and the second fixing seat and the sliding guide rod form a sliding structure;

[0036] A buffer spring is passed through the outside of the sliding guide rod, and the inner end of the second fixing seat is fixedly connected to the buffer spring.

[0037] By adopting the above technical solution, the buffer spring is set to act as a buffer when the clamping plate moves horizontally to the right, and at the same time can exert a certain leftward force on the clamping plate, so that it can stably and reliably clamp and fix the file.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows: the archive management document retrieval and placement equipment can adjust the position of the document storage board of each layer individually by setting a lifting and adjusting structure, so as to be suitable for archives and documents of different heights, and also facilitate the distinction of different types of documents. At the same time, the document storage board can move outward like a drawer, which improves the boundary of document and archive retrieval and placement. The drawer can be popped out or locked internally by simply pressing inward, which is convenient to operate. The document and archive are clamped and fixed while the document storage board moves inward by setting a clamping and fixing structure, thereby improving the stability of document placement.

[0039] 1. By arranging a transmission rack inside the primary slide, when the document storage plate is pushed inward, the transmission rack drives the second worm to rotate, and the second worm drives the second worm wheel and the reciprocating screw to rotate synchronously. The reciprocating screw rotates a certain angle to drive the limit block to move upward and engage with the secondary limit slot, thereby limiting the outward movement of the document storage plate and fixing the position of the document storage plate. When the document storage plate is pressed inward again, the reciprocating screw rotates a certain amount lower again, causing the limit block to move downward and disengage from the secondary limit slot, thereby releasing the movement restriction of the document storage plate. The operation is simple and the use is more convenient, and the documents and files can be taken and put more conveniently.

[0040] 2. By setting the threaded screw connected to the second worm, the threaded screw rotates while pressing the file storage plate inward, driving the sliding plate and the movable plate to move to the left synchronously, so that the clamping plate can clamp and fix the file files, improving the stability of file storage, preventing the files from moving when the cabinet moves or tilts, causing file confusion, and improving the reliability of file classification and storage.
